Available actions with ToolJet and REST API integration

ToolJet's integration with REST API supports various operations:

Establish connection

Provide the credentials and endpoint details, including the base URL, authentication headers, and query parameters, to connect ToolJet to any REST API. This is ideal for linking to external services, APIs, or databases.

Query REST API

Execute GET, POST, PUT, or DELETE API requests within ToolJet by specifying the endpoint and required parameters. This action allows seamless communication with external APIs for data retrieval or updates.

Set authentication

Choose the appropriate authentication method for your API connection: No authentication, Basic (username/password), Bearer (JWT), or OAuth 2.0. This enables secure access to private or protected resources

SSL configuration

Configure SSL options for secure communication with APIs. You can select from no SSL verification, CA certificate verification, or client certificate-based authentication for higher security needs.

Add custom parameters and headers

When making API calls, include custom URL parameters, headers, and request bodies. This flexibility is useful for sending dynamic values or cookies to customize the requests.

⌄

⌃

REST API stands for Representational State Transfer Application Programming Interface. It is a web service architecture that allows systems to communicate over HTTP using standard methods like GET, POST, PUT, and DELETE.

2. How do I integrate a REST API in ToolJet?

⌄

⌃

ToolJet supports REST API integration with custom headers, authentication, and dynamic URL parameters. For a REST API integration example, you can connect a public API like OpenWeather and fetch weather data in minutes, no code required.

3. Can I use REST API with Python in ToolJet?

⌄

⌃

Yes, while ToolJet itself is no-code, you can connect to any REST API Python backend or service by configuring the API endpoints and passing the appropriate request data.

4. What REST API methods are supported in ToolJet?

⌄

⌃

ToolJet supports all major REST API methods including GET, POST, PUT, PATCH, and DELETE—giving you full flexibility to fetch or manipulate data from external services.

5. What’s the difference between REST API vs API in general?

⌄

⌃

An API is a broad term for any interface allowing communication between systems. A REST API is a type of API that uses HTTP and follows specific architectural principles like statelessness and resource-based URLs.

6. Where can I learn more about REST APIs if I’m a beginner?

⌄

⌃

For beginners, a REST API tutorial from the official docs is a great place to start. Then, you can easily apply your learning by configuring API queries inside ToolJet.

7. Can I connect Java-based APIs using REST API integration?

⌄

⌃

Absolutely. If your backend is built in Java and exposes RESTful endpoints, you can connect it to ToolJet seamlessly. Just configure the base URL and headers as per your REST API in Java setup.
